My Mercury 20hp has a serial #4407955. What year and is it type B? I need parts for the water pump. It is a manual shift to reverse. How can I tell if it is a model 200?
All those in that series of serial numbers use the same impellor the part# is 47-89982 and costs about 15 bucks. Any Merc dealer will have one and you can get one at the iboats mega mall.
